Harness installation structure of link-type movable body
A harness installation structure, includes a link arm that pivotally supports a movable body to a fixed body; a wire harness that is installed to extend from the fixed body to the movable body along the link arm. The wire harness has an upwardly-extending portion which is arranged to extend vertically upwardly at an end portion of the link arm. The upwardly-extending portion is twisted in its peripheral direction while the movable body is moved between an opened position and a closed position.
1. A harness installation structure, comprising:
a link arm that pivotally supports a movable body to a fixed body;
a wire harness that is installed to extend from the fixed body to the movable body along the link arm; and
a protector that is provided on the link arm;
wherein the wire harness has an upwardly-extending portion which is arranged to extend vertically upwardly at an end portion of the link arm;
wherein the upwardly-extending portion is twisted about an axis of the upwardly-extending portion that is parallel to and alongside an axis of a shaft portion, provided on the end portion of the link arm for pivotally supporting the link arm, while the movable body is moved between an opened position and a closed position;
wherein the wire harness passes through the protector;
wherein the upwardly-extending portion is formed at a part of the wire harness drawn from an end of the protector;
wherein the protector is a slide protector; and
wherein expansion and contraction of the wire harness due to axis offset between the link arm and the slide protector are absorbed by expansion and contraction of the slide protector.
2. The harness installation structure according to claim 1 , wherein the upwardly-extending portion of the wire harness passes through a hole formed in an upper wall of a panel provided at the fixed body.
3. The harness installation structure according to claim 1 , wherein the wire harness passes through a hole formed in a side wall of a panel provided at the fixed body; and
wherein the upwardly-extending portion of the wire harness passes through a hole formed in a floor panel.
4. The harness installation structure according to claim 3 , further comprising waterproof grommets which are fitted in the hole of the panel and the hole of the floor panel, respectively; and
wherein the upwardly-extending portion is installed within the waterproof grommet.
5. The harness installation structure according to claim 1 , wherein the movable body is a door, and the fixed body is a vehicle body.
